RBI Closes FCNR(B) Dollar-Rupee Swap Window a Month Early After $52.3 Billion Inflow: What It Means for Banks and NRI Depositors

The Reserve Bank of India announced the early closure of its special Foreign Currency Non-Resident (Banks) deposit swap window on August 31, 2026, advancing the deadline by a full month from the originally announced September 30, 2026 cutoff. The facility, which permitted banks to raise FCNR(B) deposits of 3 to 5 year tenors from NRI depositors and swap the resulting foreign currency exposure with the RBI at concessional rates, attracted $52.3 billion in deposits by August 13, 2026, with total inflows including external commercial borrowings and overseas foreign currency borrowings reaching $56.846 billion.

In practice, the early closure signals that the RBI achieved its dual objectives of bolstering forex reserves and stabilising the rupee faster than expected, and banks that had been relying on this facility for dollar liquidity must now recalibrate their NRI deposit strategies.

Background: Why the FCNR(B) Swap Window Was Opened

The RBI opened the special FCNR(B) swap window in May 2026 as a targeted intervention to attract foreign currency inflows during a period of sustained pressure on the Indian rupee and elevated capital outflows. Under the scheme, banks could raise FCNR(B) deposits from NRI depositors at enhanced interest rates and simultaneously enter into dollar-rupee swap arrangements with the RBI, effectively hedging their foreign currency exposure at rates significantly below prevailing market swap costs.

The mechanism operated as follows: banks mobilised dollar-denominated deposits from NRIs, typically at rates of 6 to 7 per cent per annum for 3 to 5 year tenors, well above the 3 to 4 per cent that banks had been offering on regular FCNR(B) deposits. The banks then swapped these dollars with the RBI, receiving rupees at a pre-determined forward premium. The concessional swap rate allowed banks to offer higher deposit rates without incurring prohibitive hedging costs.

Scale of Inflows and Early Closure Rationale

The facility's success exceeded expectations. FCNR(B) deposits under the scheme reached $52.3 billion by August 13, 2026, prompting the RBI to advance the closure date. In its announcement, the central bank cited the "encouraging response to the swap facility for FCNR(B) deposits and the resultant forex inflows" as the basis for early termination.

Key operational details of the closure:

Deposit acceptance deadline: August 31, 2026. Banks could no longer accept fresh FCNR(B) deposits under the special swap facility after this date.
Swap availment deadline: September 11, 2026. Banks had until this date to execute swaps with the RBI against eligible deposits already mobilised before August 31.
Regular FCNR(B) deposits: Unaffected. Banks can continue to accept standard FCNR(B) deposits outside the special swap arrangement, though without the concessional swap pricing.
Existing deposits: FCNR(B) deposits already raised under the scheme continue to maturity. The closure applies only to new deposit mobilisation under the facility.

Impact on Banks

Deposit Rate Recalibration

Banks that had been offering enhanced rates of 6 to 7 per cent on FCNR(B) deposits under the swap facility will need to revert to market-determined rates for new deposits. Without the RBI's concessional swap, the all-in cost of raising FCNR(B) deposits increases substantially, and banks are expected to reduce NRI fixed deposit rates by 100 to 200 basis points over the coming weeks.

Liability Management

For banks that raised significant volumes under the scheme, the existing FCNR(B) deposits create a known liability maturity profile over 2029 to 2031. Banks will need to plan for the eventual redemption of these deposits, which at maturity will require either dollar outflows or rollover at then-prevailing rates. The concentration of maturities in a narrow window could create forex demand pressure in 2029 to 2031 if not managed proactively.

In practice, treasury teams at banks with large FCNR(B) books should begin modelling the maturity concentration risk now and consider staggering their hedging strategies rather than waiting until closer to the redemption dates.

Impact on NRI Depositors

NRI depositors who placed deposits before the August 31 deadline are unaffected and will continue to earn the enhanced rates for the full tenor. However, new NRI depositors from September 1 onwards face a different landscape:

Lower returns: FCNR(B) deposit rates have already begun declining as banks withdraw the enhanced rates that were economically viable only with the RBI's swap support.
Alternative instruments: NRIs seeking dollar-denominated returns may shift to NRE fixed deposits (which offer rupee-denominated returns with full repatriation) or explore the RBI's liberalised remittance scheme for outbound investments.
Tax treatment unchanged: FCNR(B) deposit interest remains exempt from Indian income tax under Section 10(15)(iv)(fa) of the Income-tax Act (now the corresponding provision under the Income-tax Act, 2025), providing a continued advantage for NRIs in higher tax brackets.

Forex Reserve and Rupee Implications

The $56.8 billion in total inflows under the facility has provided a significant boost to India's foreign exchange reserves, which stood at approximately $658 billion as of late August 2026. The intervention helped arrest the rupee's depreciation trajectory, with the currency stabilising in the 86.5 to 87.5 range against the dollar during the scheme's operation.

However, the eventual unwinding of these positions when deposits mature will create a corresponding outflow obligation. The RBI's own swap book will unwind over the 2029 to 2031 period, and the central bank will need to ensure adequate reserve buffers to manage the dollar demand at maturity without market disruption.

Historical Precedent

The RBI has deployed the FCNR(B) swap mechanism twice before in modern history. In September 2013, during the taper tantrum, the RBI opened a similar window that attracted $34 billion in deposits and is credited with stabilising the rupee from its then record low of 68.85 per dollar. In November 2013, an additional swap window for overseas foreign currency borrowings complemented the FCNR(B) scheme. The 2026 iteration was larger in scale, reflecting both India's increased NRI deposit base and the severity of the capital outflow pressure that prompted the intervention.
